We thought "American Idol" Jordin Sparks was looking particularly svelte when we saw her in the audience during the April 26 taping of "Dancing With the Stars" -- but this settles it.

The 21-year-old singer posted a fairly revealing photo to Twitter on May 1, writing "I don't know why but my bathing suit reminds me of fruity pebbles."

The resemblance between the orange-and-blue bikini and the sugary breakfast cereal is up for debate, but she's certainly looking a lot fitter these days.

Hollywood Life recently reported that a strict regimen with a trainer has already led to a 30-pound drop in weight for Sparks.
